Definitions
- the invention relates to a method for controlling a Compressor according to the preamble of the claim 1.
- Such a method is usually used to Compressor before an overload or due to overheating Protect damage by the compressor in good time before damage occurs is turned off, giving him an opportunity cool down again. Damage can e.g. at the pressure valve occur, for example as a result of embrittlement and resulting surface damage, which leads to leaks in the valve. Furthermore, the piston ring can be damaged, what to destroy the piston ring and consequently too can lead to a piston seizure.
- DE 196 21 946 C1 is a control arrangement for known a compressor, based on experience an estimate of the operating temperature of the compressor is determined. If one is exceeded The compressor can set the specified temperature threshold then be switched off automatically. Furthermore is known from DE 198 12 234 A1, the heat transfer conditions in the vicinity of the compressor, z. B. based on a corresponding model analysis, and depending on this estimated data Then control the compressor.
- the invention is therefore based on the object Specify methods for controlling a compressor, frequent use of the compressor when the compressor is used well Avoids switch-off processes.
- the invention has the advantage of switching off of the compressor above a temperature limit a particularly simple and manageable control of the Enable compressor. Another advantage is that by the pressure medium system, in which the compressor Pressure medium, e.g. Compressed air, can convey, caused Back pressure when determining the temperature limit is taken into account. This allows a further improvement in the protection of the compressor against overload while at the same time making optimal use of it of the compressor. Ultimately, the As a result, the compressor can be made smaller.
- the compressor Pressure medium e.g. Compressed air
- Another advantage of the invention is that they are advantageous for any type of compressor control can be used, e.g. for pressure regulator or governor regulation, for via a mechanical coupling from one Drive, e.g. an internal combustion engine, uncouplable Compressors or for those driven by an electric motor Compressors. The latter is described below discussed in more detail.
- one Drive e.g. an internal combustion engine, uncouplable Compressors or for those driven by an electric motor Compressors. The latter is described below discussed in more detail.
- the invention has the further advantage also the electric motor or those particularly at risk of damage Parts like brush bridge and motor windings to prevent damage caused by overheating.
- the insulation of the motor windings can be protected from melting.
- a temperature sensor to determine the temperature intended.
- This has the advantage of being further improved To enable exploitation of the compressor, since the Temperature at a particularly critical point in the Compressor can be precisely determined using a temperature sensor and is therefore not an estimate for security reasons relatively large tolerances taken into account should be necessary.
- This can be a special small and compact compressor used be, which is also relatively inexpensive.
- thermo modeling In a further advantageous embodiment of the invention is the determination of the temperature value via a thermal modeling by calculation intended. This can also affect the temperature sensor to be dispensed with.
- Both variants of the invention are temperature sensors and thermal modeling, provided in The temperature sensor signal is normally accessed and only if there is a defect or malfunction of the temperature sensor the thermal modeling alternatively used to determine the temperature value becomes. This can result in particularly good operational reliability be achieved.
- the air suspension system shown in Fig. 1 for a vehicle comprises four air bellows (1, 2, 3, 4), which each cushion one wheel of a four-wheel vehicle.
- the air bellows (1, 2, 3, 4) are pneumatic Lines with 2/2-way valves (6, 7, 9, 10) connected.
- There is also an air pressure reservoir (5) provided via a pneumatic line is connected to a further 2/2-way valve (8).
- a pressure sensor (11) For sensing the pressure in the storage container (5) is a pressure sensor (11) with the storage container (5) connected.
- the valves (6, 7, 8, 9, 10) are on the pressure medium side to one another via further pneumatic lines Air dryer (14) connected with regeneration function.
- the air dryer (14) has a regeneration function known type on the compressed air from the Air bellows (1, 2, 3, 4) or the storage container (5) via the valves (6, 7, 8, 9, 10) into the air dryer (14) flows back and via a regeneration path can be released into the atmosphere, taking moisture is dissipated.
- the air dryer (14) is on the pressure medium side with a Compressor (13), e.g. B. a piston compressor more common Design, connected.
- a Compressor e.g. B. a piston compressor more common Design
- the one on a shaft from an electric motor (15) driven compressor (13) sucks a suction connection (17) to air from the atmosphere.
- By switching on the electric motor (15) can be compressed Air is generated and to which the pressure medium system (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 14) air suspension system be delivered.
- valves (6, 7, 8, 9 10) are electromagnetic Actuated valves designed and with their electrical Connections on the one hand with the electrical ground connected, on the other hand with an electronic control unit (12) which is used to control the following functions described in more detail. Furthermore is the air dryer (14) to activate the regeneration function via an electrical line with the Control unit (12) connected. In addition, the electric motor (15) for activation via an electrical line connected to the control unit (12).
- the pressure sensor (11) and a particularly temperature sensitive one Place the compressor arranged Temperature sensor (16) is more electrical Lines connected to the control unit (12). Furthermore is with the control unit (12) z. B. from that Driver of the one equipped with the air suspension system Connected to the control element (18) to be operated, with which the setting of different vehicle levels, e.g. an upper, a middle and a lower Levels, is possible.
- the respective vehicle level or the respective level on the individual struts the vehicle is measured using suitable displacement sensors, which is not shown in FIG. 1 for the sake of simplicity are. These displacement sensors are of a known type also connected to the control unit (12).
- the control unit (12) processes these input signals of the pressure sensor (11), the temperature sensor (16), the Control element (18) and the displacement sensors and generated control signals for the electric motor (15), the Air dryer (14) and the valves (6, 7, 8, 9, 10).
- the air suspension system shown in FIG. 1 works like follows:
- control unit (12) on one or more struts a discrepancy between that caused by each Displacement sensor measured level position and a target level position, determined on the basis of the control element (18) is determined, it controls what is assigned to the shock absorber Solenoid valve (6, 7, 9, 10) on, causing the valve from its blocking position in a open position is switched. If the level is increased should and thus increases the air mass in the air bellows must be controlled by the electronic control unit (12) in addition to the solenoid valve (8), causing pressure medium from the storage container (5) in the respective Air bellows (1, 2, 3, 4) can flow. Depending on what you want Pressure in the air bag and existing Pressure in the reservoir (5) switches the control unit (12) optionally the electric motor (15), causing the compressor (13) to operate will be generated and a higher pressure level may still exist in the reservoir.
- valve (8) remains closed and the compressor (13) is switched off.
- the air dryer (14) is in the regeneration position switched, causing compressed air from the to bleed the air bag into the atmosphere can. This also causes unwanted moisture deposited.
- the storage container (5) serves, as previously indicated, a rapid increase in air mass in the Air bellows and thus a quick lifting of the level to enable. Because of the comparatively small Delivery rate of the compressor (13) can only an air mass increase in the air suspension bellows more slowly cause. Therefore, it is appropriate that the reservoir (5) constantly at a sufficient pressure level is held or if there is a drop in pressure, the desired sufficient pressure level as quickly as possible is restored. In addition, the compressor should not be overloaded and if possible for a requested level increase for To be available. This is advantageous with the procedure described below.
- the air suspension system described above can essentially differentiate between two operating modes be, namely the mode of operation for filling the reservoir (5) and the operating mode for direct conveying the compressed air from the compressor (13) in the air bellows (1, 2, 3, 4).
- the compressor (13) In the operating mode filling the reservoir, the compressor (13) achieve a relatively high pressure level, so for a later transfer of the pressure supply from the storage container (5) in the air bellows (1, 2, 3, 4) in one adequately short time a sufficient pressure difference is available. Since this mode of operation of not directly to the user of the air suspension system is perceived, but runs in the background, so to speak, can also speak of a background mode become.
- this pressure sensor can be dispensed with in that a distinction is made between discrete operating modes and corresponding temperature limit values (T 2 , T 4 ) are assigned to these operating modes. Since the respective back pressures of the pressure medium system are known or can be determined in a simple manner in the operating modes, these temperature limit values (T 2 , T 4 ) can be determined very simply by tests.
- the temperature limit value (T 2 ) of the background operating mode is deliberately chosen to be significantly lower than would be necessary to avoid damage to the compressor (13) or the electric motor (15).
- the compressor (13) and electric motor (15) are kept at a lower temperature during the filling of the reservoir, so that a certain runtime of these elements is immediately available for the main operating mode of filling the air bellows and without a cooling-off period.
- This has the advantage that the air suspension system is readily available to the user and the filling of the storage container (5) runs in the background without noticeably reducing the availability for the level adjustments. This is particularly important when the pressure in the storage container (5) is so low that the storage container (5) for lifting the vehicle cannot yet be switched on and the lifting must therefore take place via the compressor (13).
- FIG. 2 shows a Temperature / time diagram of the temperature signal (T) of the Temperature sensor (16) for a certain period of time. Starting from time 0 when the compressor (13) is put into operation for the first time, this increases Temperature signal (T) according to line (20) after an exponential function on.
- the value (T 2 ) is effective as the temperature limit, so that the compressor (13) is switched off again when this value is reached.
- the temperature signal (T) decreases according to line (21).
- the value (T 1 ) is effective as the switch-on temperature, so that the compressor (13) is switched on again after cooling to this lower temperature level.
- the temperature increases according to line (22).
- the compressor (13) is then switched on and off alternately, as can be seen from the temperature profile represented by the lines (21, 22).
- the temperature following line (20) continues to increase according to line (23) until the temperature limit (T 4 ) effective for this operating mode is reached.
- the compressor is then switched off, which results in a temperature drop according to line (24).
- the effective switch-on temperature (T 3 ) is reached, the compressor is switched on again, the temperature increases according to line (25) until the temperature limit (T 4 ) is reached again.
- the compressor (13) is alternately switched off and on again, as can be seen from the temperature profile represented by the lines (24, 25).
- the temperature hysteresis is i.e. the distance between the temperature limit and assigned to the same operating mode Switch-on temperature, for the background mode chosen significantly larger than for the main operating mode.
- the comparatively has lower temperature hysteresis of the main operating mode for this mode of operation the advantage that the break times for cooling the electric motor are relatively low, so that a user of the air suspension system a noticeable Progress was made in raising the level becomes.
- FIG. 3 shows an advantageous embodiment of the invention, in which time criteria are subordinate to the temperature signal-dependent switch-off criteria for the compressor (13).
- the temperature signal (T) rises at the compressor (13) which is switched on for the first time in accordance with line (30).
- the temperature switch-off criterion would only be reached at the temperature limit (T 2 ).
- the corresponding temperature profile up to the temperature limit (T 2 ) is shown by the dashed line (31).
- t max a time limit for switching off the compressor (13) has already been reached at the time (t max ).
- This premature switch-off of the compressor has, for. B. with a cold compressor the advantage that the pressure valve is particularly protected, since this then reaches a critical temperature faster than it from the temperature signal (T), which, for. B. detects the cylinder head temperature of the compressor (13) is displayed. Since the cylinder head temperature does not rise as quickly as the temperature of the pressure valve at low ambient temperatures, the pressure switch criterion described above can be used to better protect the pressure
- the temperature signal (T) decreases in accordance with the line (32).
- the compressor (13) would be switched on again when the switch-on temperature (T 1 ) was reached, that is to say after a relatively short cooling time. 3 is also switched on again according to a time criterion , namely when a predefined cooling time (t cool ) has been reached. Only at this point in time is the compressor (13) switched on again, which can be seen in the temperature curve on the line (33).
- a time criterion namely when a predefined cooling time (t cool ) has been reached.
- the superimposed control according to time criteria is preferred applied at low outside temperatures, i.e. if the temperature at the cylinder head of the compressor (13) due to good heat dissipation to the environment only slowly when the compressor (13) is switched on increases and quickly when the compressor (13) is switched off sinks again.
- the control has an effect Time criteria supportive of a reduction the starting frequency of the compressor (13), without reduce availability.
- the ambient temperature are not sensed separately, but can be calculated indirectly from the temperature profile determined by means of the temperature sensor (16) be determined on the cylinder head.
- the electronic control unit (12) takes into account the time criteria for switching off (t max ) and for switching on again (t cooling down ) primarily in relation to the temperature limit value (T 2 ) and the switch-on temperature (T 1 ). This means that after the time limit (t max ) has expired, the compressor (13) is switched off, even if the temperature limit (T 2 ) has not yet been reached. The compressor (13) is only switched on again after the predefined cooling time (t cool ), even if the switch-on temperature (T 1 ) is not reached.
